There is.

It isn't.

e sharp (a white key) is a semitone above f flat (another white key) and
your proposed procedure would have been oblivious of that.

That is different to the situation between f sharp and g flat (which
your proposed procedure is designed for) since there is an actual black
key between f and g.

I let LilyPond _calculate_ that semitone of difference.  Apparently the
code example was too obtuse.  I would not have thought so since we were
talking about Scheme code in the first place, but then I am probably
more skilled talking with computers than humans.
